    Arrow Parallel Arrays

    Hi

    I have the following code, and want to express the max points result in parallel with the winners names (i.e the two couples who got 7), What do i need to do to amend this code at the bottom?

    Code:
    var contestantNamesArray = ['bob and pete', 'tim and jon', 'mick and alun', 'van and brad', 'chez and jaz'];
    
    var judgesPointsArray = [2,1,5,4,3];
    var audiencePointsArray = [4,5,2,3,1];
    
    var combinedPointsArray = new Array (5);
    
    for (var points = 0; points < judgesPointsArray.length; points++) 
    {
        combinedPointsArray[points] = judgesPointsArray[points] + audiencePointsArray[points];
    }
    
    
    var maxPoints = combinedPointsArray[0]
    
    for (var points = 0; points < judgesPointsArray.length; points++) 
    {
    	if (combinedPointsArray[points] > maxPoints)
    	{
    		maxPoints = combinedPointsArray[points];
    	}
    }
    document.write('The maximum number of points was ' + maxPoints + '<BR>')
    
    
    
    document.write('The couple(s) scoring the maximum were:' + '<BR>') 
    
    
    {
    document.write(contestantNamesArray[maxPoints] );
    }
    
    Thanks

            winners.push(points); // save the winner
    		maxPoints = combinedPointsArray[points];

    Thanks, it's not quite what i'm after doing.

    I dont want to assign another variable, i.e "winners", so is there a way of doing it?

    Not if there is a possibility of multiple winners.
    You could combine the first 2 for loops:
    Code:
    if ( (judgesPointsArray[points] + audiencePointsArray[points]) >= maxPoints)
